Abstract

This paper studies the shear and peel strength of composite AA1050 aluminum and SS 316 steel manufactured by accumulative roll bonding (ARB) process. The ARB samples were tested for shear and peel strength under a single axial tensile test. The layer strength was measured in each sample and the results of the experiments were compared. The results showed that the shear strength of layers was higher than the peel strength; also the microstructure of the sheet after performing 5 cycles of the ARB process was observed. To test the strength of the samples during different passes of the process, tensile tests were carried out; the results indicated a general increase in strength. Further studies on the scanning electron microscope (SEM) images of the fracture sections of the samples showed that by increasing the number of passes, the thickness of the steel layers was less than that in the pass 3 of these layers to tear. In the following, hardness changes along the sheet thickness were studied in successive passes. The results indicated that the pass 2 had an impressive increase in hardness.
